Airworthiness Directive · Amendment 39-21137 · Communications
Cirrus Design Corporation Airplanes
This AD applies to Cirrus Design Corporation (Cirrus) Model SF50 airplanes, serial numbers 0005 through 0176 and 0178, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Cirrus Design Corporation (Cirrus) Model SF-50 airplanes. This AD was sent previously as an emergency AD to all known U.S. owners and operators of these airplanes. This AD requires disconnecting and removing the headset amplifier and microphone interface circuit card assemblies for the 3.5 mm audio and microphone jacks. This AD was prompted by a cabin fire incident that occurred on a Cirrus Model SF50 airplane during ground operations where the operator observed smoke exiting from behind the right sidewall interior panel. The FAA is issuing this AD to address the unsafe condition on these products.
Before further flight, disconnect and remove the headset amplifier and microphone interface circuit card assemblies by following the Accomplishment Instructions, steps A. and G. through K., of Cirrus Alert Service Bulletin Number SBA5X-23-03, dated February 7, 2020.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
